IWS Pro Flood & Drain Grow System - Big Punch (10.5l) Inner Pots

The IWS Flood & Drain is a fully automated feeding system that takes the strain out of tending to larger numbers of plants. This system has been a customer favourite for over a decade, and there are very good reasons for that: it's simple to set up and run, it makes tending to commercial scale gardens quick and easy, it allows you to control feed times with complete precision.

The Pro version is equipped with thicker, 25mm (internal diameter) pipe and fittings, compared to the 13mm pipe used in the standard version. This improves nutrient flow, allowing you to flood and drain the system more quickly. There's also an extra drain pump inside the brain, which halves the time it takes to send nutrients back to your tank!

Big Punch Inner Pot (holds 10.5 litres of medium). These inners hold more medium and come with drainage holes just at the bottom, making them ideal for maximising root-space with bigger plants. They work well with clay pebbles, coco or 60/40 (clay/coco).
